Question / Help Distorted frames in video being caused by hard drive bottleneck?

I've been trying for a while now to figure out what is causing the distortion in my videos. Here is an example without and with this distortion:

It sort of resembles screen tearing. I posted once before here if you want more information, but my current thought is that it is being caused by a hard drive write speed bottleneck. I have tried h264 and h265 (both NVENC) lossless (qp=0) and high bitrate recordings, and all of them run into the same problem. During my tests I didn't see my CPU or GPU being overloaded, but it seemed as though my hard drive was reaching 100% occasionally.

My first question is pretty simple, is this a probable cause? I really don't understand how encoders write to a drive, so I am just assuming they can't buffer frames to write later. But maybe I'm wrong, idk.

If this is the case, is there any way I can test this theory other than just tabbing out during a recording and checking my disk in the task manager? I didn't see anywhere in log files where this sort of information is displayed.

Lastly, if this is indeed the issue, what can I do about it, other than just recording less data? Is there a setting I can use somewhere that will cap bitrate dynamically? Thank you in advance for your help.

May as well rule out other possibilities first.

Is your game FPS capped?
Is Windows 10's "game mode" disabled?
I don't own a NVIDIA card at the moment to test it fully but have you tried the "Indistinguishable" preset yet?
